SHAKER FOR, FIRE-GBATES.

Application filed April 2, 1909.

To all whom it may concern:

Be it known that we, Anonri-r THOMAS Zn'ncrr and GUSTAV HENRY DIEMER,citizens of the United States, residing at Trinidad, in the county ofLas Animas and State of Colorado, have invented new and usefulImprovements in Shakers for Fire-Grates, of which the following is aspecification.

This invention relates to improvements in shakers for fire grates suchas are used in stoves and furnaces.

The object of the invention is to provide a shaking mechanism which isentirely independent of the grate bars and has shaker bars which arecaused to remain between the grate bars to shake out the ashes andcinders and stir the coals.

In the accompanying drawings Figur 1 is a sectional view of the ash pitof a furnace. showing the shaking mechanism. Fig. '1 is a detailelevation partly in section of the shaking mechanism. Fig. 3 is a planof. the same.

The base portion of a furnace, forming the ash pit is indicated. at 1and the grate bars at 2 bearing on supporting flanges 3 with which thefurnace base is provided. In the ash pit under the grate is a pair ofstandards a here shown as provided with outstanding bases 5 which may bereadily secured in place by bolts 6. The said stand ards are connectedtogether by a rock shaft 7 which has its bars in openings near the upperends of said standards. Said rock shaft is provided at its center with adepending rock arm 8. At a suitable point near the base of the furnaceis a standard 9 in which is mounted a rocking lever 10, the lower end ofwhich is connected by a link rod 11 to the lower end of the rock arm 8.It will be understood that by means of the said lever and connectionsthe rock shaft may be readily oscillated. To the end of the rock shaftare secured rocking bars 12 and below the said rocking bars 12 arerocking bars 13 which are parallel therewith and are pivotally mountedon the standards a as at 14. The rocking bars 12 are connected togetherby the rods 15 and the rocking bars 13 are connected together by rods16. T-shaped shakers 17 are disposed to operate in the spaces betweenthe grate bars and have their downwardly extending arms 18 pivotallymounted on the rods 15, 16 so that Specification of Letters Patent.

Patented Nov. 30, 1909.

erial No. 487,504.

the said shakers are carried by the parallel rocking arms 12, 13 andwhen the latter are operated by the lever and connections hereinbeforedescribed the said shakers are caused to move vertically in the spacesbetween the grate bars so as to shake out the ashes and cinders and stirthe coals in the bottom of the fire as will be readily understood.

When our improved shaking mechanism is used the grate bars may beentirely stationary and it is only necessary to move the grate bars inorder to replace them when burned out.

Having thus described the invention what is claimed as new is Z 1. Incombination with grate bars of a furnace, a rock shaft mounted below thegrate bars, rocker bars having their central portions connected to saidrock shaft. rocker bars parallel with the first mentioned rocker barsand having their pivots disposed centrally thereof and mounted below therock shaft, and pivot devices connecting the ends of the said rockerbars, and shaker elements mounted on said pivot devices for verticalmovement so that the shaker elements at opposite ends of the rocker barsmove simultaneously in reverse directions, said shaker elements beingdisposed for operation in the spaces between the grate bars, and meansto actuate said rock shaft to impart motion to said rocker bars andshaker elements.

2. In a shaking mechanism of the class described comprising supportingstandards, a rock shaft mounted thereon and having a rock arm, parallelrocker bars some con nected to the rock shaft and others pivotallyconnected to said standards, shaker elements having depending arms, rodsconnecting the parallel rocker bars and connected to the depending armsof the shaker elements to support and actuate the latter, and a leverconnected to the rock arm of the rock shaft to actuate said rock shaft,said rocker bars and shaker elements.

In testimony whereof we affix our signatures in presence of twowitnesses.
